Bordered by the foothills of the Bavarian Forest and the banks of the Danube, the historic abbey of the municipality of Niederaltaich is already an attractive destination due to its natural surroundings alone. The Benedictine monastery of Niederaltaich, founded in 731 or 741 by Duke Odilo of Bavaria and settled by monks from the island monastery of Reichenau on Lake Constance, is the starting point for the development of today’s village. On a hill in the then uninhabited part of the estuary of the Isar River, the monastery was consecrated to St. Mauritius and the first abbot Eberswind called the place Altaha (Altwasser).
